This is a pack of two optional RPM Front A-Arms, and are intended for use with the Losi Mini 8IGHT buggy. These RPM A-arms have a beveled 30° leading and trailing edge and beefed up shock and anti-sway bar mounts. The outer hinge pin support diameters have been beefed up to almost double the thickness of the stock A-arms, while a more modest increase in size has been designed into the inner hinge pin support diameters as well. Each RPM A-arm for the Losi Mini 8IGHT is molded in black out of an extremely tough blend of nylons. If speed is your thing, you need RPM armor on your ride!

So far, so good. I find the stock delrin A-arms to be too fragile - they break a lot. I tried the GPM aluminum versions - but they transmit too much stress. (I broke the aluminum suspension mount within a half-hour).
These seem to be between the two extremes. Holding up so far.

RPM Front A-Arm (Black) (Mini 8IGHT)

These work great with the stock plastic casters and hubs with no trouble for close to 3 months til I got the losi aluminum casters. But they don't work with the losi aluminum casters without grinding away in couple spots to make smooth. Then they break when landing off bigger jumps. It rips the hingepin out on passenger side everytime. Everyone at my track with this setup has broke in the same way. Need a RPM 2.0 arm made to replace.

RPM Front A-Arm (Black) (Mini 8IGHT)

Over all I love RPM parts, I have had them on many RC's however first time out with these on my mini8 and the left side broke at the pin on a very soft hit. I hope I just got a bad one, and the replacement will be stronger, but I was disappointed with that.
